'I'his invention relates to a'multiple counter calculating and; registering machine, wherein the counting mechanisms are brought into operative position relatively to their driving means by a movable frame in which they are provided. It is known in connection with machines of this type to move the counting mechanism frames, which are designed as carriages or rotatable drums, by a special source of power but these machines have the drawback that the setting of the counting mechanisms, that is to say the movement of the counting mechanism frames, is dependent on the extent of the movement of their controlling member, for instance,

the paper carriage. It is therefore not possible in connection with these machines to bring into operative position any desired counting mechanism with the slightest movement of the paper carriage or even by a key depression.

The present invention obviates these drawbacks.

A constructional form of the invention is shown by way of example in the accompanying drawings, wherein the counting mechanisms are provided in a drum.

Figure 1 is a longitudinal section through the machine.

Figure 2 is the arrangement of the drum as viewedfrom above.

Figure 3 is a view of the locked setting keys.

Figure 4 represents the adjustment by studs as viewed from above.

Figure 5 is a diagrammatic view thereof as viewed in front.

Figure 6 is an end view of some keys.

Fig. 7 is a fragmentary horizontal sectional view taken through the lower parts of the keys and showing the arrangement of the bell crank levers connected therewith;

Fig. 8 is a transverse sectional view through the toothed bar showing one of the guide bails therefor.

The counting mechanism drum is mounted below the bed plate 1 on a shaft 2 which is secured by bearings 3 and 4. The said drum comprises a hub 5 and side walls 6 and 7 which bear the axes 8 of sixteen counting mechanisms 9. These counting mechanisms are driven by rack bars 10 which are connected to the type ov carriers 11 of the machine. The counting mechanisms are brought into operative position relatively to the said driving means by rotating the drum. In the construction shown by way of example the control for the drum is arranged in such a manner thatit can'be eifected automatically by the movement of the paper carriage of the machine as well as independently thereof by depressing keys. For this purpose there are provided in the front left part of the machine two rows of keys with 60 eight keys in each row so that a key is provided for each counting mechanism in the drum. The keys l2 are each formed of two parts, an upper part and a lower part; the upper part is provided with a button and is moved in slots of the guides 13, 14 carried by side walls 15, 16 and abuts with its longitudinally movable neck against the lower part 19. The lower key parts 19 are moved in slots between two further guides 17, 18 which are 70 also secured to the side walls 15, 16. They are each provided with a pin 20 at their lower end. There is provided on the guide 18 a locking bar 22 which is subjected to the action of a spring 21. The locking bar 22 is provided 75 with slots through which the key parts 19 extend. If one of the keys 12 is depressed, the locking bar will be forced apart by the projection 23 ofthe key part against the tension of the spring 2l and the bar 22 will jump 80 over the projection 23 as soon as the part 19 is pressed low enough as is shown in Figure 1 in connection with the depressed key. If another key is depressed, its projection 23 will again open the locking bar 22 so that the previ- 85 ously depressed key will return to its normal position in consequence of the tension of a spring 39 the arrangement and operation of which will be hereinafter described. The locking bar 22 is provided with two rows of slots 90 so that it acts on both rows of keys. Bell crank levers 24 are rotatably mounted at the a side frames 15, 16 on stop screws 25 and their bifurcated arm'engages with the pin l20 of the lower key part 19. The bell crank lever 24 is 95 connected to a link 26 the other end of which isconnected to a lever arm 27. The lever arm 27 is secured on a shaft 28 which is mounted between two side plates 29, 30. The extended shaft 2 of the counting mechanism drum ex- 100 tends through a third bearing 31 below the bed plate 1 andthe hub of this bearing is turned in such a manner that the bushing 32 which is riveted in the plate 30 ts over the same. The plate 30 is prevented by a screw 33 from being 105 twisted and from sliding olf the turned end of the hub. The plate 29 is secured to the plate 30 by means of bolts 34, 35, 36 and nuts so that the two plates :onstitute a double-sided bearing for the shaft 28. There is secured between the two plates on the shaft 28 a stop or abutment 37- which cooperates with a lever arm 38 which is rigidly secured to the shaft 2 and is also located between the two plates 29 and 30. There is connected to the lever arm 27 a spring 39 which always tends to draw the stop 37 out of the path of the arm 38 into the position indicated in Figure 1- by dotted lines. By means of the link 26 and bell crank lever 24, the depressed key 12 and the lower key end 19 are again returned to the normal position when another key is depressed.

Since in the present case the counting mechanism drum has sixteen counting mechanisms, sixteen stops 37 are also provided between the two walls 429 and 30 and the lever arms 27 are connected by links 26 to the corresponding keys 12 or to their bell crank levers 24.

In order that the setting or adjusting arm 38 of the counting mechanism drum may move from its vposition of rest to the new stop 37 when depressing one of the keys 12, a special source of power is provided whereby the counting mechanism drum or its setting arm 38 is always rotated in the direction of the arrow. In connection with the calculating machines with manual drive a spring motor is preferably employed for the said purpose; din'ing each operation of the machine the spring of the said motor is tensioned and the motor therefore always maintains its full power. In the present case it is a question of a machine with electric drive; consequently the `rotary movement for the drum is preferably driven directly therefrom. An intermediate shaft 40 which is adapted to automatically return the paper carriage to its end position is constantly rotated by the motor of the calculating machine in the direction of the arrow. The said shaft has a sprocket wheel 41 by which a wheel 42 is driven through the medium of a chain the said wheel 42 being loosely mounted on the drum shaft 2. A friction clutch 43 is provided between the sprocket wheel 42 and the shaft 2 so that the counting mechanism drum would always rotate in the direction of the arrow if its setting arm 38 would not prevent it from doing so by one of the stops 37. By depressing a further key 12, the previously operated key will be released again, as already described, and will be jerked upwards by the tension of the spring39 .whereupon its stop 37 will move out of the path of the setting arm 38 so that the latter may now freely rotate until it abuts against the new stop 37.

Means are provided in the present machine whereby the counting mechanisms of the drum -may be brought into operative position relative to their driving means 10 not only by the keys 12 but also automatically through the medium. of studs 72 which are previously adjusted on the paper carriage or on another movable part of' the machine. For this reason, the keys 12, 19 are made of two parts and the upper key part has a slot 44 Figure 6 through which a bar 45 providedfS-with rising surfaces extends. Consequently there is located in each row of keys a'bar 45 one end of which has a hole 46 wherein a pin 47 of a hand lever 48 extends. The lever 48 is rotatably mounted on a stationary pin 49 in the side frame of the machine and its lower arm is designed as a segment 50 engaging with a toothed wheel- 51 which is keyed on a shaft 52 mounted below the bed plate of the machine inthe brackets 53, 54. A second wheel 55 which is rigidly secured to the otherI end of the shaft 52, drives a toothed bar 56 which engages with its other end-with another toothed wheel 57 which is rigidly secured to the lower end of an eccentric shaft 58. The bar 56 is maintained in engagement with the toothed wheels by bails 59, 60 which are secured to the bed plate of the machine. The eccentric shaft 58 is provided with its turned ends 61, 62 in bearing brackets 63, 64 which are secured by screws 65, A66 to the side frame of the machine.

Sixteen levers 67, 68 engage with their eyes over the eccentric 58 the said levers being superposed and spaced apart by guiding fingers 69, 70. The said guiding fingers are secured to the frame walls of the machine. The levers 67, 68 are provided approximately in their center with projections 71, 71' cooperating with one of the studs 72. The tapered end of the lever arms is provided with links 73 the other end of which is connected to the bell crank levers 24. In the position shown in Figure 4, a stud 72 presses against the projection 71' of its corresponding levers 67, 68 whereby the latter is swung into the position as indicated. Its link 73 thereby swings the corresponding bell crank lever 24 and through the medium of its link 26, the corresponding arm 27 is swung against the tension of its spring 39 and the setting member 37-scon nected to the saidlever arm is moved into the path of lthe setting arm 38 of the drum.

Owing to the handle 48 being shifted out of the position 48 into the position' shown in Figure 3, the two bars 45 have locked all the keys by their inclined teeth 45' which extend through the slots of the keys after they have also raised the upper .part of the last depressed key the lower part 19 of which is however left in the depressed position and is only freed from this position by the adjustment of a new stop 37 by studs 72 or levers 67, 68. The lower key part 19 belonging to the newly adjusted stop 27 is then arrested by the locking bar 22 in the same manner as previously described.

In order that the hand lever 48 may be brought out of its position 48 into the position shown in Figure 3, its toothed end 50 through the medium of the toothed wheel 51 causes the shaft 52 to be rotated through an angle of about 180. By means of the toothed bar 56 engaging with the toothed wheel 55 and through the medium of the toothed wheel 57, the eccentric shaft 58 is also rotated through an angle of about 180 whereby the ends of the setting lever 67 are swung in such a manner that the projections 71 of the levers come within the range of the studs. By shifting the hand lever 48 not only the keys 12 are prevented from operating but also the levers 67, 68 are brought into operative position by the rotation of the eccentric shaft 58. The hand lever 48 is secured in its end positions by a spring actuated check lever 74 which cooperates with a pin 75 of the lever.

A cage is secured between the side walls 76, 77

position by a pawl` 82. There are provided in' the plates 78, 79 sixteen rows of slots wherein studs 72 may be inserted. The vertical spacing of these slots is the same as the vertical spacing of the setting levers 67, 68 so that the studs 72 correspond in their elevated position with 150 the projections 71. The operation of these parts is as follows:

In order to work in vertical columns on a sheet, the sheet is placed around the writing roller 83 in the paper carriage 76 the tabulating device of which is adjustedby studs 84 in the known manner so that when operating the machine the paper carriage moves from one stud 84 to the next one. The relative spaces of the studs 84 represent the width of the columns of the sheet. When the columns are divided by inserting the studs 84 the cover 80 will be opened and a stud 72 inserted in the slots of the plates 78, '79. It is readily obvious that the selection of the counting mechanism which is to work in the respective column is only dependent on the height of the row of slots wherein the respective stud 72'is.inserted. When the stud 72 is coordinated in accordance with the intended work to the tabulating studs 84 the cover 80 will again be closed whereby the stud 72 will be prevented from falling out.

f If Vthe adjustment or setting of the counting mechanisms is now automatically effected by the carriage movement through the medium of studs 72, it is nevertheless still possible notwithstanding the adjusted studs 72 to also work in each column with any of the counting mechanism than that which is coordinated to the stud if this should be necessary for some reason or other. For this purpose merely the handle 48 is again brought into the position 48 whereby the keys 12 are again freely depressible. At the same time the shaft 51 and the transmission rod 56 of the eccentric 58 are moved through the medium of the segment 50 in such a manner that the projections 71 of the setting arms 67,V

y 68 move out of the range or path of the studs 72. The counting mechanism operated by the studs 72 of the respective column remains in operative positionand its stop 37 remains in the path of the setting arm 38 of the drum because the corresponding lower key part 19 is arrested by' the locking bar 22. When another counting mechanism is operated by the depression of keys a new stop 37 is inserted and the lower key part 19 previously arrested in the operated position thereby returns to the normal position in the above described manner. It is thus possible to work in each column of the sheet with any desired counting mechanism notwithstanding the adjustment of the studs 72.

The herein described counting mechanism control is so arranged that machines may be supplied wherein the control is effected automatically by studs previouslyA adjusted on the paper carriage or also machines without paper carriage wherein the counting mechanisms are operated by keys. Moreover machines may be supplied wherein both setting systems are provided as shown in the drawings.
